SpaceX is planning first relaunch of Falcon 9 rocket

SpaceX CEO Elon Musk will relaunch one of his used rockets this fall.

“Fourth rocket arrives in the hangar,” Musk tweeted on Tuesday. “Aiming for first reflight on Sept/Oct.”

The message from Musk, included a photo of the four reusable rockets that have been successfully recovered by the company.

On May 6, SpaceX successfully landed the first stage of one of its Falcon 9 rockets on a floating barge in the Atlantic Ocean.

The rocket had launched from Cape Canaveral and delivered the JCSAT-14 communications satellite for the Japanese telecom Sky Perfect JSAT Corp.

Landing Falcon 9 rockets on platforms at sea could save SpaceX millions of dollars on future rockets. Traditionally the first stage of rockets crashed back down to earth and became unusable.

SpaceX has not yet announced the payload that will be carried by the reusable rocket on its second flight. The firm has several private satellite launches on its schedule, and it also has a contract with NASA to supply the International Space Station.

SpaceX’s next launch will take place at Cape Canaveral on June 14, according to its Twitter account.

The company is also planning to take humans to Mars by 2025.

There is no set launch date for SpaceX’s reusable rocket at this time.
